Use the systematic treatment of equilibrium to determine the pHand concentrations of species in 1.00L of soln containing 0.065 molcitric acid (H3A), 0.025 mol 8-hyrdoxyquinoline (HB) and 0.040 molKOH. Consider just acid-base chemistry. Ignore ion pairing andactivity coefficients. Citric acid is a triprotic acid withpKH3A=3.128, pKH2A=4.761, and pKHA2-=6.936. HB is derived from thediprotic acid H2B+ with pKH2B+=4.94 and pKHB=9.82.
What is: pH, [H3A], [H2A-], [HA2-], [A3-], [H2B+], [HB], [B-],[H+], [OH-], [K+]
I would greatly appreciate it if you could please show all work.I haven't the slightest clue on how to approach this problem. Thankyou in advance.
